GREASE-CUP.

Specification of Letters Patent.

To all whom it may concern.

Be it known that I, OSCAR ZERK, a subject of the Emperor of Austria-Hungary, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Grease-Cups, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This-invention relates to grease cups of the type wherein there is a member having a tubular opening communicating with the hearing and formed with a surface adapted to support the grease, and a cap screwing onto such member and adapted to force the grease throughthe opening, there being a spring detent to prevent inopportune displacement of the cap.

The object of the invention is to simplify and cheapen the construction of such grease cup and to render it more eflicient.

To the above mentioned ends I make the stationary member, commonly called the cup, in a form which may be stamped and having a non-circular bore; and I provide a tongue occupying such bore and connected with a head within the cap above the grease, and a suitable spring adapted to restrict the free rotation between the. tongue and the cap. This spring I form in a peculiar manner, which increases its elficiency and durability, while allowing it to be carried with the greatest convenience within the cap.

The characteristics of the invention may be best summarized as consisting of the combinations of elements hereinafter described and summarized in the claims.

The drawings clearly illustrate my invention.

cup complete; Fig. 2 is. a vertical sectional section thereof; Fig. 3 is abottom plan;

which stands diagonally Figure 1 is a side elevation of the grease this having a non-circular bore, preferably a square bore, as shown at 12, and above the upper end of this portion is an outwardly extending annular portion 13, from which extends a downward flange 14;, which is screw-threaded on its exterior. The bore 12 is continued, preferably in the form of a tapered bore 15, through the threaded end 11 to the end of the cup. The top-surface of the annular portion 13, together with the angular bore and thetapcred bore carry the grease.

The cap is designated 20. It has a cylindrical wall internally threaded'substantially throughout, and a 'top plate 21. Where these join, there is an outward head, which is made into a series of projections 22 having radial walls by being slotted across. This provides efiicient means whereby the cap may be grasped and turned. The cap is preferably a stamping, and the projections are preferably made bya punch, punching through the bead formed by the stamping.

3O designates a thin, fiat tongue, which preferably has a widened lower end 31, within the square bore 12" The widened portion of the tongue is of greater width than a side of the square bore, (being preferably of just slightly less width than the diagonal of the bore) wherefore this tongue may move up and down in the bore, but. cannot rotate therein. Atits upper end, the tongue is swiveled in a disk 40, which is slightly concaved upwardly and rests against the under surface of the top of the cap. This swiveling may be easily accomplished by simplyupsetting the upper end of a central projection 32 extending upwardly from the-top, the hole in the disk which the projection occupies preferably flaring upwardly.

5O designates a spring,.which lies within the cap beneath the disk 40 and has arms 51 engaging the tongue 30.- The resilience of this spring compels .it to rotate with the cap, and, as the tongue cannot rotate, the spring, during the rotation, is forced backwardly by the tongue and then springs against the opposite side, with the result that the cap may be rotated in'periodic steps, half a rotation each. The spring 50, in order to be effective and insure long life, has a coil 52 on each side between the cir- Patented June 11, 1912.

does not bend thespring about a single line,

but throughout the whole coil 52. A very durable spring is thus provided. The spring occupies a slight depression or recess 53 in the wall of the cap above the threads. By

having the tongue narrower where the spring engages it than where it engages the square bore, the bore may be comparatively large and at the same time the restraining effect of the. spring not be excessive.

With my grease cup, the parts are formed with a maximum of simplicity and cheapness, the cup, the cap, the tongue and the head may each be a stamping made with great cheapness, and the spring, while very effective, as described, is also simple and cheaply constructed. The parts are very easily assembled, the upsetting of the end of the projection 32 swiveling the tongue to the disk, and the insertion of the spring holding these parts in place.

Having thusdescribed my invention, what I claim is 1. In a grease cup, the combination, with a cup member and a cap member screwing one onto the other, of a tongue and a spring mounted in and carried by one and the same member, the spring frictionally bearing on the tongue, whereby the movable member 1s held'against premature movement and the tongue slides but does not rotate in theother member. s

2. In a grease cup, the combination, with a cup member and a cap member screwing one onto the other,' of a tongue slidable but non-rotatable in one member, and a spring mounted withi n the-other member and havin a pair of armsengaging the opposite si es of said tongue, said arms-being connected with the bowed portion of the spring through theintermediacy of coils.

3. In a grease cup, the combination, with a cupmember having external threads and a cap member having internal threadsgscrewing onto the cup member, of a flat tongue slidable but non-rotatable in a non-circular bore of the cup member, and a spring mounted within the cap member and having a pair 1 of arms engaging the opposite sides of said tongue, said arms being connected with the" bowed portion of the spring through the intermediacy of coils.

4:. In a grease cup, the combination, of a vcup having a. non-circular bore and a threaded exterior and a cap having a threaded. interior and screwin onto the cup, a disk within the cap'at its upper end,'atongue swiveled in said disk and occu ying the bore, and a spring rotatable wit the, cap and frictional y engaging the tongue. j 2' 5. In a grease cup, the combination of a cup having a square bore and a threaded e'xterior and a cap having athreaded interior and screwing onto the cup, a disk within the cap at its upper end, a fiat tongue swiveled to said disk and occupying a diagonal position in the square bore, and a spring frictionally engaging the fiat side of the tongue.

6. In a grease cup, the combination of a cup having a non-circular bore and a threaded exterior, a cap having a threaded interior and screwing onto the cup, a disk within the capvat its upper end, a tongue swiveled in said disk and occupy ng, the bore, and a spring within the cap engaging the tongue, said spring occupying a recess in the inner wall of the cap and standing beneath the disk and serving the double purpose of holding the disk in place and retarding the rotation of the'cap independently of the tongue.

7. In a grease cup, the combination of a cup having a non-circular bore and a threaded exterior, a cap-having a threaded interior and screwing onto the cup, a disk within the cap at its upper end, a flat tongue swiveled in said disk and occupying the bore, a spring within the cap engaging the tongue, said spring occupying a recess in the wall of the ried by the cap member and frictionallybearing against the tongue.

. 9 In a grease cup, the combination of a cup member externally threaded, a cap mem- -ber internally threaded and screwing onto the cup member, a tongue rotatably carried by the cap member and non-rotatably but slidably engaging the bore of the cup memher, and a. spring carried by the capmemher and bearingagainst the tongue.
